The Igloo Model Viewer Pro is a Unity -based Based application which has been designed to seamlessly import , display and explore 3D models in an Igloo immersive spaceand display a wide range of 3D model formats, and supports both 2D and 3D projection.
Requirements
An annual subscription license is required and the software is enabled using a license key.
Formats
The model viewer supports OBJ, FBX and GLTF/GLB file formats.
Features
The application window appears as shown below, with menu items on the left hand side and model preview on the right hand side.
...
Load Model from File - Loads the desired 3D model from a location on the server. After clicking the button, you will be shown a file browser to select the desired file.
Load Model from URL -
Save Placement - Saves the rotation and scale of an object. These settings will be automatically applied when the object is loaded back into the viewer.
Load Skybox from File - Load a HDRI file (.hdr) as the skybox.
Clear Skybox - Unload the skybox file.
Object Scale - Change the scale of the object uniformly in the X, Y, and Z axes.
0.1x - Scale by 0.1.
10x - Scale by 10.
100x - Scale by 100.
Rotate - Quick rotate buttons.
X - Spin the object in the X axis 90 degrees.
Y - Spin the object in the Y axis 90 degrees.
Z - Spin the object in the Z axis 90 degrees.

Load Model
Selecting the Load Model button will display the Load Model panel:
...
From here there are six preset models that you can load to get a feel for how to use the software.
To load your own custom model, simply click the “Load model” button at the bottom of the panel. If you would like to use this model consistently, you can use the “Save model” button to save and overwrite one of the existing preset models.
Once you have loaded a model, the buttons that are greyed out will become active.
Save Viewpoint
...
This will save the current orientation and scale of the model, meaning the next time you load it in, you will not have to apply the effects again.
Load Background
...
Here there are some preset backgrounds that you can select from. Alternatively, if you would like to upload your own equirectangular images (.png, .jpg, or .hdri) then you can click the “Load background” button to select a custom image to use.
...
It is recommended to use as high quality images as possible.
Remove Background
...
This button will simply remove any custom background you have loaded in and will return to the grey background.
Transform Model
...
The transform model tab will allow you to transform the model’s scale and rotation.
The buttons at the top (0.1x, 10x and 100x) will change the slider values from 0.1-1, 1-10, and 10-100 allowing you full control over the scale of the object.
The rotation buttons will allow you to quickly rotate an object in any of the axis by 90 degrees.
The reset button will reset all rotation and scale values back to the default.
Camera Movement
...
Camera movement will allow you to control the position of the igloo viewer from within a pop out menu. Simple press in the direction you would like to go and the camera will move in that direction until you press a different button, or press the same button again.
Jump to centre of the model will jump you to the centre most point of the model.
Viewing Mode
...
Viewing mode will allow you to change how you view the object.
Flythrough - standard ghost mode where you can fly in any direction wherever you cursor is facing.
Wrap - this will change the wrap within the space of the model, for example if you wanted to move the object onto a different wall.
Orbit - This will give you orbit controls so you can move relative to the centre of the object. Simple click and drag to orbit around an object.
Render Streaming
...
Stream - Allows for the Model Viewer to be controlled from Igloo ICE Control Panel with a mouse and keyboard and the same UI.
...
same controls. This will need to be setup as an app in ICE Control Panel as a custom browser in custom_browers.json:
| Code Block |
|---|
"ModelViewerPro": {
"name": "Model Viewer Pro",
"url": "$remoteIP/receiver/index.html",
"https": false,
"icon": "$ai/image.png",
"description": "Model Viewer Pro"
} |
And in the config.json:
| Code Block |
|---|
"apps": [
"matterport",
"streetview",
"warping",
"default",
"modelViewer",
"openStageControl",
"blockade",
"ModelViewerPro"
], |
A web server will start automatically when you press start streaming which is located here:
C:\Program Files\Igloo Vision\Model Viewer Pro\Model Viewer Pro_Data\Managed\webserver.exe
...
Watch Folder
A watch folder can be setup in “C:\Program Files\Igloo Vision\Model Viewer Pro” so that a model will be automatically loaded after any model of an accepted format automatically gets loaded in once it has been copied into that folder. Create Simply create a new folder and call it “WatchFolder”.
Command Line Arguments
You can specify the path to a model file using a command line argument when starting up the Model Vieweradd command line arguments to the .exe for the model viewer to specify loading a model as soon as the application is opened. To do this , simply add the “-loadModel” argument, followed by the path of the model you want to open. e.g:
-loadModel "C:\ModelViewer\ModelViewer-0.22\Igloo3DModels\Architecture\hintze_hall\scene.gltf"
...
Additional command line arguments
-presetModel [0-5] - Will automatically load the preset model from the specific slot. Example: “-presetModel 2” will load the skeleton model.
Templates
Templates can be used to set specific rotation, scale or translation values to an object whenever it is imported. This is useful when a consistent transformation is needed in the workflow between Model Viewer and another application. To select a template simply use the drop down box and select from a existing one (not tested). To create your you own, navigate to the StreamingAssets folder, and open an existing template, alter the values as necessary, and save it under a new template name. The template must be save with “config_” first. e.g: “config_[Your_Template_name].json”. The drop down box in Model Viewer Pro will auto populate with any files saved this way.
| Code Block |
|---|
{
"scale": {"x": 1, "y": 1, "z": 1},
"rotation": {"x": 0, "y": 90, "z": 0},
"translation": {"x": 0, "y": 0, "z": 0}
} |
Controls
Movement - As is with every other Igloo application.
...
Orbit - Move round the object in an orbit mode.
Streaming Setup
This requires setup in Igloo Control Panel as a custom browser called ModelViewerPro in custom_browers.json:
| Code Block |
|---|
"ModelViewerPro": {
"name": "Model Viewer Pro",
"url": "$remoteIP/receiver/index.html",
"https": false,
"icon": "$ai/image.png",
"description": "Model Viewer Pro"
} |
And include ModelViewerPro in the apps list in the config.json:
| Code Block |
|---|
"apps": [
"matterport",
"streetview",
"warping",
"default",
"modelViewer",
"openStageControl",
"blockade",
"ModelViewerPro"
], |
A web server will start automatically when you press start streaming which is located here:
